Metal complexes of N-m-nitrobenzenesulfonylamido-meso-tetraphenyl porphyrin: M(N-NSO2(m-NO2)C6H4-tpp) (M=Zn2+, Ni2+, Cu2+) and Tl(N-NSO2(m-NO2)C6H4-tpp)(OAc) (tpp=5, 10, 15, 20-tetraphenyl porphyrinate)
摘要:
The crystal structures of N-m-nitrobenzenesulfonylimido-meso-tetraphenylporphyrinatonickel(II) [Ni(N-NSO2(m-NO2)C(6)H(4)tPP), 3], N-m-nitrobenzenesulfonylimido-meso-tetraphenylporphyrinatocopper(II) [Cu(N-NSO2(m-NO2)C(6)H(4)tpp), 4], N-m-nitrobenzenesulfonylimido-meso-tetraphenylporphyrinatozinc(II) chloroform solvate [Zn(N-NSO2(m-NO2)C(6)H(4)tPP) CHCl3; 5 CHCl3] and cis-acetato-N-m-nitrobenzenesulfonylimido-meso-tetraphenylporphyrinatothallium(III) chloroform solvate [TI(N-NSO2(m-NO2)C(6)H(4)tpp)(OAc) CHCl3: 6 CHCl3] have been established. The coordination sphere around the Zn2+ ion in 5 CHCl3 (or CU2+ ion in 4) is distorted square planar (DSP), and for the Tl3+ ion in 6 CHCl3, it is a distorted trigonal prism (DTPR). The ion-dipole interaction between the Ni2+ ion and the nitroaryl group dipole enforces that Ni2+ in 3 preserves a distorted square planar pattern, but in addition the NO2 moiety of the N-substituent is in close contact at the apical site.
